This invention relates to improvements in crusher mill driving means. I

It is one of the objects of the present invention to provide a crushermill driving means in which the driving mechanism may be easily removedfrom the crusher Without disturbing the crusher head shaft or sleeve, orthe crusher head shaft and sleeve may be removed without disturbing thedriving mechanism. I

A further object of the invention is to provide a crusher mill drivingmeans in which the driving means and the crusher head sleeve arejournaled on conical rollers in a manner to permit the easy separationof some of the partswithoutdisturbing others, which is of considerableimportance inrepair or replacement of parts.

A further objectof the invention is to provide a crusher mill drivingmeans having a means for forcibly oiling all of the bearings of thedriving mechansim, and also the bearings of the crusher head shaft andsleeve.

A further object of the invention is to provide a crusher mill drivingmeans which is of simple construction, is strong and durable, and iswell adapted for the purpose'described. In the accompanyingdrawinginwhichthe same reference characters indicate the same no partsin all of the views:

Fig. 1 is a vertical sectional viewof the lower portion of the improvedmill; and Fig. 2 isa horizontal sectional view thereof taken on line 22of Fig. 1. 7

Referring to the drawing, the numeral 5 indicates a lowerframe'or casingwhich is of cylindrical for-m and is provided with an inner :upwardlyextending bearing 6' which terminates at its lower end. a distance above0 the lower portion of the casing.- A vertical .45 sleeve shaft, and thelower end of the sleeve shaft isrsupported ona conical roller bearing 10which is interposed betweensaid lower end portion of thesleeveisha-ftiand the removable cap plate 11 forming part of the casing5.

.59 An annular'shoulder 11' holds the bearing bricated :from the samesource.

in position. As constructed the downward strain of the crushing head isborne by the sleeve shaft and from said sleeve shaft to' the frame, thusmaterially differing from crushers in which the strain is borne by theshaft of the head. i

A. bevel gear 12 loosely mounted on and keyed to the lower end portionof the sleeve shaft 'T'is' in mesh with and drivenby a bevel pinion 18which is mounted on the inner end of a horizontal driving shaft 14. Saiddriving shaft is journaled in conical roller bearings 15 and extendsthrough the side exten sion frame or casing 16 and at its outer end isprovided with a pulley 17 for connection with a source of drive, notshown.

The horizontal shaft 14 and its bearings 15 extend through and aresupported in a supplemental frame or casing 18, of cylindrical form incross section, which extends into the extension casing or frame'16- andat its inner end portion has an annular and shouldered connection 19therewith. A medial portion of the supplemental casing is formed with anannular longitudinal flange 20 which snugly fits into the extensionportions of the casing 5 toprevent lateral movement of the supplementalcasing. 'Said supplemental casing is also provided with a radial flange21 which isspaced a slight distance from the end of the casingextension16 and is formed with openings for receiving b'olts'22 to firmly clampthe shoulder 19-against the side of the casing 5 and hold thesupplemental casing firmlybut easily removably in position. I a

i The horizontal shaft 14 also has a geared connection 23 with anoil'pump 24 for forcing oil to various portions of the mill. A pump 24connectedto an oil tank 25 draws the oil, therefrom and forces it intothe cocentric bore of the vertical sleeve by means of the pipe 26. Thesleeve shaft 7 is formed with a duct 27 to permit the passage of the oilto the upper portions of the milL; The Crusher "shaft, the lowerbearing, the gears and bearings'of the drive shaft are also lu- Thesleeve shaft 7 is also-provided with an outer duct 28 forlubricating thebearing of the sleeve.

A pipe 29 extending upwardly from the gearing chamber 30 is provided forpermitting the return of the oil from upper portions of the mill. Fromsaid chamber the oil flows through the cap duct 31 to the return pipe 32and to the oil tank 25, thus providing for a constant circulation of oilthrough the mill.

A duct 33 permits the oil to flow from the gear chamber 30 to the shaftand gear chamber 34 to lubricate the bearings of the shaft 14, and areturn pipe 35 connected to the chamber 3% and the oil tank returns theoil from said chamber to the oil tank.

A tubular casing part 36 connects the pump to the supplemental casing 18by bolts 36' so that when desired the tubular casing may be easilyremoved to separate the pump gears 23 from each other. v V

The pump shaft 37 is formed in two parts connected together by a keyedcollar 38 which permits the easy separation of the shaft parts.

Particular attention is directed to the fact that the driving portion ofthe mill forms a unitary structure or is self-contained with the casingso that in use it is notnecessary to provide a separate bearing for theouter end portion of the horizontal shaft as in the ordinary mill. Thisconstruction also permits the use of a shorter horizontal or countershaft. I

From the foregoing description it will be seen that the crusher milldriving means is of very simple construction and provides a direct andpositive drive and a force feed lubricating means for oiling all ofthebearing parts. It will further be seen that the construction permitsthe separation and removal of parts with the minimum amount of labor.
